IMPROVMENT IN MACHINES FR BUR'RING WOOL, &c.

, The Schedulereferred to in these Letters Patent and; making partvofthe same.

To all whom zt muy concer-n i v Bc it known 'that I, WILLIAM RIcHanAsoN,of Oldham, in the county of Lancaster in England, have invented certainnew and useful Improvements in lilachincry i'or Burring or Cleaning`Wool, Cotton, and othcrfibrous materials; andI do hereby declare thatthe following .is a full, clear, and exact description thereof, whichwill enable 'ot-hers skilled in the art to make and usc 'the same,reference being had to the accompanying drawingl fonning part of `thisspecification.

My invention refers to those dcscriptrionsci" burring orAcleanin'g-machines in which a f tine-comb cylinder-7 is employed, andfrom which burrs, seeds, and

.other impurities are stripped, while the cleanedmaterial is carriedforward -to be removed by a 'revolving brush, or similar apparatus, andconsistsv Firstly, in thev employment, in .combination with two or moresuchiinc-comb cylinders, of sets or series of rollers and brushes,arranged 'as hereinafter 'describcd, whereby the material fed to thesaid cylinders is operated upon in a'pcculi'ar and effective manner.-

Secondly, in the' use of certain apparatus whereby thc rejected materialfrom the first cylinder is trans# i'crred back to the last cylinder, orto the same cylinder again when one only is used,withont being mingledwith the incoming fresh' material, and `whereby the said rejectedmaterial is further deprived of burrs, seeds, or other impurities, 'andis also, to a certain extent, opened out.' l

In order to explain, the operation of these pointsof novelty, Ishall-havcto refer inpgeneral terms to some. ordinary working parts of aburring or cleaning-machine,but will subsequently point ont that whichIclaim as my invention; v

Figure 1 represents in section a machine-constructed according to myinvention, and

Figures 2, 3, aml'4, 'detache'd views of myv transferring apparatus, theconstruction ot' which will be described after Ij have pointed outv thcgeneral operation of the machine.

The feed-apron upon which the'inaterial is placed barring-machine, andto the several parts of whichV is shown at D, carried by thc'frame a.This apron, by its traveling motion', `delivers the fibrous material tothe spiked feedfroller dV and dish c,.by which it is transicrredto thebeater-blades f, mounted upon the cylinder c, andthe dirt separatedfalls through a grid g'.

At h' is what is commonly called the tine-comb cylinder, provided withcombs -7t.

Beneath this cylinder is a roller, l, in which is fixed a' parallelseries of notcl1edbla1`les,.fm, extending around its circumference, and.at n isv another similar roller, beyond which is a rotary brush, 0. v

The cylinder h is provided with a casing 1), an

extension of whichincloses revolving disks {[which Acarry crossbars frfurnishedI with brushes s,' revlving in contact with the combs It.I

Within the casing p are also cages t, such as are .used inscutchers andother machines of that class, and from which 'air is exhausted in ytheusual man-4 ner.; but these cages are not necessarily used.. B eyondthese cages lare rollersP 'u,\vl iich deliver the material to thetrzweling-apron o.

The arrangements for driving the various parts are notvshown in" thedrawing, as they may-be of any ordinary character; but in order `to leadto my linvention l will, in ih e trst place, point out the usual "action.of theoperatingparts; v y

The material placed upon the traveling' apron b is, conveyed thereby tothedishand roller c d, the `latter j of which passesjit .forwardto'thcaction of the` blades f, bywhich it is toruaway in a partiallyopened state andthrown' toward the fine-comb cylinder h and'rolle'r l,the blades m of which feed it to the combs In The Isaid blades m,however, retain a certa-in portion, andl this is removed from them bythe roller n and trans ferr-cd, to a great extent,` to the combs 7:; andany material remaining-on the roller n is removed 'and fed tothe combsl.; by the brush o, The' combs k thus become charged with tufts of thematerial which arrive iu contact. with vthe roller u, and this, by .itsrapid rotation, removes burrs; and other impurities,

together with 'some fibrous material, and throws them downward from themachine. Af'\t'e,1- tl1is, the rotating vbrushes s, acting againstA thematerial, strip it.rfrom the combs )aand pass it through the casing p tothe cage t, from whence it is conducted by the rollers u tothe travelingapron c, to be removed in any requiredlcondition.v A' Y llt-'will beseen by the foregoing description that, as the roller n has yto stripthe roller-L the surface speed of the` former must be the greater, andthat the surface speed of the brush o must be greater still, and thatthe same remark applies to the brush sin reference tothe cylinder h. f

Having thus alluded to the workingof an ordinary as Yabove described, lmake no claim, I will proceed to point out the distictive feature of thefirst part. of rmy invention. i y

Beyond the roller fw, and running clearof it, is 1a' second 1inccombcylinder h in connection with which there are transferring-rollers l n.and brush c', and corresponding c the roller fw isa second roller, w. Ithas been escribed, in reference to the cylinder h, that the' burrs,seeds, and other impurities, are

finally detached by the roller w, and it has been assumed that when sodetached they fall to the bottom of the machine but,accordin g to myinvern,

ving x.

tion, I transfer them to the second tine-comb cylinder h', again toundergo 'the treatment ,already reforred to.

' The second part of my invention relates to a special method ofeffecting this transference, but I willat present assume that the'roller w dischargesv the removed portions upon the Wroller Z, which,together with the'next roller and brush, is inclosed in acaslhese beingthe conditions, the material will be carried upward by vthe roller Z'and fed to the cylinder It', the other roller ot'imd brush o' performingthe same operations as as those described in reference to the first set,l a o. i

After thc charged combs 7c' have passed the-brush 7 othey meet with therevolving roller w', which strips theremaining burrs, 8m., casting themdownward,as I will now assume, into any convenient receptacle.

The combs charged with cleaned material passingv onward, meet with therotating'brnsh s, which, be

' ing `placed midway' between the two cylinders, acts as a stripper forboth,and the said Amaterial is delivered as before described. 'y

In order toshow-,theL-object of my invention, it should be observed thatthe burrs, ac., which are cast down according to the usual mode ofopera-ting, contain a certain amount of fibrous material, and,

in some cases,'it has been proposed to return them to the machine toundergo a second operation@` but in such cases' they have become mingledwith the incoming raw material so as to pass with it to the finecombcylinder, or they Vhave been mingled with it upon the said cylinder;but, according to my invention, the bnrrs and other impure parts are notreturned thereto, but pass on to the second cylinder h', from which theyare removed and cast downward by the roller l'w'. Instead-however, ofallowing the roller 'w' to throw the bui-rs and mixed fibrous' materialsat once i'om thc machine7 I prefer to conduct them back 'to thel rollerl', so that they may again be taken by the line-comb cylinder h', andthe second part of my invention consists in a special ar-v rangement forthis purpose, which I will now proceed to describe, referring to fig. 1,above mentioned, and to the detached views, figs. 2, 3, 4, which arevdrawn upon an enlarged scale.

Atl is a grid, carried by. a frame, 2, which is :at-- tached to theframe-work of the machine. Beneath this grid ,is a frame 3, providedwith cross-bars 4, on which are mounted rows of spikes, 5, capable ofprojectinghrough the bars, `of the said grid'.

To the framef are-'jointed connecting-rods 6, ex-` tending from cranks-7upon shafts'S, provided with spurewheels 9, -andthesev two shafts aregeared' together by'anintermediate wheel, 10,",y i

' To the4 frame 3 are also jointed connecting-rods '411,' extendingii'oln cranks 12 upon a shaft, 13, which is driven bypulleys Y14 15, thelatterbeing on the axis of the comb-cylinder 7|-, and upon this shaft 13lis a spnr-wheel,16, which, by means of" an intermediate wheel, 17,drives thespnr-wheel 9 on one of the. axes 8. Y

The operation of this `part of my invention is asfollo'ws,.assumingthat-the burs or other impurities, together with acertain amount ot' fibrous material., are driven by the roller w' ontothe grid'l, and that the freed impurities fall at once through the saidgrid:

set forth;-

Tlhe rotary motion of the cylinder a will, by means of the pulleys 1415, spur-wheels 16, 17,9, impart rotatory motion to the cranks 7, while,at the same time, the shaft 13 will he driven, and rotatory motionlwillbe given to the cranks 12.

cranks 12 ready to be again thrust upward and carried forward.

vBy this traveling motion of the spikes 5 the spaces of the grid arckept from being clogged by the lrejected material beneath the roller w',andthe refusemattersare. thereby enabled to fall through,as abovedescribed);l and when they are above the grid the material is, to acertain` extent, opened and deprived of a further quantity ofimpurities, which fall through the grid, while,'at the samebtime,thebrons material is' carried forward by the said spikes and fed totheroller l and is by it conveyed along the shield a: and once morepresented to the fine-comb cylinder' h, to be'operated upon asabovedescribed.

lAt 20` is the fan employed for exhausting the cages t, by means of anair-trunk, 21, from which there proceeds another trunk or channel, 22.rlhistrunk forms a ,portion'of the frame-work of the machine., andcarriesvon itsy outside the axis 23 of the tine comb-cylinder, -the endof which is formed with apertures 24;

4 During the operations of the machine, as above describe'th'the t'an 20exhausts the 'air throughthe trunk land apertures 24, thereby'establishinga partial vacuum in the fine-comb cylinder,y and causing theiibrous-material to be drawn onto its surface and to be retained thereuntil stripped by the means abovementioned, thesaid current of air alsocarrying oli" dust and other fine particles.' Y

As regards the first part ot' my invention, I have shown and' describedtwo ne-comb cylinders, but

three ormore may. he employed if desired, after the manner-aboveexplained.

As regards the second part oi' my invention, it may -be'adapte'd tomachines ,with one cylinder only, by
